VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 353,654, dated December 7, 1886.

Application tiled May 12, 1885. Serial No. 165,181. (No model.)

To all whom t may concern,.-

Be it known that we, MICHAEL C. ARMO'UR and FRANK G. BIELEFELD, both of Chicago, in the county of Cook and State of Illinois,

have inventedl certain new and useful Improvements in Vapor-Burners for Use in Various Applications, of which the following is a specification, reference being had to the accompanying drawings,and to the lletters of ref- Io erence marked thereon.

The invention is herein described more particularly for application to vapor-stoves.

The object of this invention is, first, to overcome the blowing and pufling of the flame so r 5 common to gasoline-burners, and which heretofore has been only partially overcome by packing theburner-pipes with asbestus, gravel, or similar substances, the presence of which is objectionable, from the fact that small parti- 2o cles will work into the aperture of the needlevalve and obstruct the flow of Vapor. In order to assist in producing a steady ilame, we provide a generating-chamber of much greater capacity than is ordinarily used; and in order to heat said chamber effectively and rapidly we adopt means wherebya more effective flame is produced than has been heretofore provided, so that the vaporization of the gasoline is almost instantaneous.

The object of our invention is, secondly, to provide means for working the needle-valve and cut-OHU'or regulating the-dow of gasoline, and consequently the flame) simultaneously, or by the same act or moven1ent-that is to say, by the simple movement of a lever the cutoff is brought over the needle-point and the iiame reduced to a minimum, still remaining lighted, and by another movement of the said lever the cut-off is carried away from the 4o air-tube, allowing tl'ie flame to burn .at the cap or burner proper.

The third object of our invention is to employ one generator for the vapor-ization of gasoline for its own burner and other burners, as

hereinafter set forth.

In the accompanying drawings, Figure l shows a side elevation of our improved generator and burner, applied in a manner hereinafter specified. Fig. 2 is a vertical section of Fig. l. and burner from another point of view. Fig. 4

is a Vertical section. Fig. 5 is asectional plan on the line x x of Fig. 3, showing in full lines the cutoff, hereinafter described, open, and the same in dotted lines closed, the full lines showing the lever in the position which it occupies when the needle is at its lowest point, and the dotted showing the position of the lever when the needle is at its highest point and the flame extinguished. Fig. 6 is a vertical 6o section through Fig. 4, the line of section be-y ing such that the pipe eis cut out, or not seen. Fig. 7 is a top View of the burner-cap, hereinafter described. Fig. S is aside view of the same. Fig. 9 is an under side view of the 65 same.

Similar letters of reference indicate similar parts in the respective gures.

Referring more particularly to Fig. 4, the vapor-burnerleads by the pipe a to the gaso- 7o line-tank. (Not shown.) The pipe a has communication by means of a threaded thimble,a, with the interior of the cistern c, a small jetopening, b, being provided in the thimble, through which the gasoline enters the cistern. The thinible is threaded, so as to be vertically adjustable. A vertical pipe, e, reaches from the lower part ofthe cistern, connecting it with the generator f. The lower end of the pipe is sealed by the gasoline, and is threaded,so as to 8o be adjustable. e

The generator f is constructed with an annular space, f', surrounding the wall f, thespacef being in communication with the pipe e. The annular space within the generator causes the gasoline to take almost a complete circuit before ignition, whereby the iiuid is effectually heated. The lower part of the generator is inclosed for the greater portion of its diameter by the cup g, which is secured to 9c I the under side of the generator by screws g', and the generator is surmounted by a cap, g. (Shown more particularly in Figs. 7, 8, and 9.)

A vertical needle-valve, h, screws intoatube, h', which unites by a branch, h, with a chanl- 95 ber, i, which connects by means of the pipe Fig. 3 is an elevation of the generator 5c` .an air or induction tube, m', which extends through the central aperture of the generator, communicating with the cylindrical or crown portion of Athe hat-shaped cap g. the base of the air-tube m turns the colla-r n of the lever n', which lever has 'an arm, n", oonnecting with the handle n and with the lower part ofthe needle-valve h, as shown in Fig. 6.

A tube, if', is connected with the lower part of the chamber t, said tube carrying a horizontal needle-valve, h4, having a handle, hf. The opposite end of the tube i is provided with a disk, 01', screwed thereon. The horizontal needle-valve h4 is only used, as hereinafter described, where one burner is employed to generate vapor for itself and other burners.

The cut-off o is pivoted or hung by a support, o', arranged between the tubes e fi', as shown in Figs. 3, 4, and 5, 'the operationof which cut-off is as follows: On the lower face of the collar u of the lever n is formed a pin or projection, p, which enters a slot, Alo', made in the upper part of the cut-off, so that as the lever is turned movement is imparted to the cut-off, which turns upon its pivot in one direction or the other as the lever is moved.

The following is the operation, it being understood that the burner is only generating. vapor for itself, the needle -valve h* being closed: When the needle-valve h is closed by turning lever n into the position indicated in dotted lines in Fig. 5, cut-off o, also connected with but moving in a direction opposite to that of lever n', stands with its right extremity over jet-aperture Z. Supposing the apparatus to be cold, the gasoline on being admitted to the pipe a strikes against the top of the cistern c and finds its way up the tubee'to the generator f. Lever n being now turned to the left, needle-valve 'h is lowered, aperture l partly opened, and the gasoline descends pipe i, Fig.

6, and, passing through the horizontal branch' A h, reaches the needle-valve aperturel, is deected by the concave bottom of cut-oft' o, which is still suspended in position over aperture l,and trickles down the sides ofthe vertical pipeh to the drip or igniting cup k. Thereupon the supply through jet-openingl must be shut off entirely. The gasoline in igniting-cup la having beenignited, the flame is directed toward the generating-chamber, passing up on each side of cutoff o, suspended above the l, cup, and the heating of the generator begins.

n almost consumed, the cut-off must be movedl When the gasoline in the igniting-cup has been f so as to partly open the needle-valve aperture l. The generator having been heated by thel burning of the iiuid in the igniting-cup la, the

lever must then be thrown fully over, soA as to p Aroundy that indicated in full lines in Fig. 5, Vin which' cut-off o is moved away from over needlevalve aperture l and from under air-tube m, leaving a free passage for the gasoline up into the air-tube. The ignitionat the burneroccurs immediately with the opening of the aperture, the gasoline shooting up with atmospheric air through the air-tube m into the spaces ggof the cap,and falling thence through the annular space `q` to the cup g, from whicha supplemental iiame arises, the object of which isto heat the burner. A .portion of the mingled atmospheric air and gasoline which is projected into space q escapes vthrough radial with a series of perforations, r, and the flange or brim with a series of slots, 1", `the perforations and slots being in line, Figs. 4, 7, and 8, the effect of the union of the two series of `iets (viz., those emanating from `the perforations and those from `the slots) being a greenish flame, which is found to be much more effective than the flame rdinarily produced in gasoline-burners? Now, supposingthe flame to be full on and it is desired to stop cooking without extinguishing the iiame, the lever n must ,be moved from the position shown in full lines in Fig. 5 to such position as is indicated, say, by the dotted line z, which has the effect of nearly closing the needle-valve aperture Z and nearly shutting off the iiow of vapor through -said aperture to the burner, a small flame continuing to burn. l

A special feature of our invention is, therefore, a lever having the double function of operating the needle-valve and thecut-off.

The cistern c is used with a view of increasing the area of the generating-surfaces and separating the vapors from the supplyv of gaso-. line, so as to keep the vapors from interfering with the free delivery of the gasoline into the generating-chamber. The separation of the generating-chamberfroni the cistern provides practically for the generator a lower part or bottom, which is neither affected by sudden changes-of temperature nor the bubbling of the entering fresh and cold gasoline. The box' or cistern c is made convex on the top, this shape allowing water or other uids accidentally spilled upon it to run Voff quickly. The cistern furnishes, lin fact, a cushion of air and vapor above the gasoline, upon which elastic` cushion the column of gasoline in the pipe e rests.

By the construction above described the flame is found toburn steadily under the most difficult conditions-such as the presence of cold-air drafts or the heat of an oven in close y proximity to the burner, under which conditions the iiames from burners of other descriptions are found to blow and puff and to be generally unsatisfactory.

In Figs. l and 2 is shown the application IOO IIO

IIS

of the invention to a three burner stove, the construction being such that the vapors are generated by one burner for itself and the other two burners. The stove is shown by A, the lids of which are represented by s, an extension-shelf being shown by t. The gasoline is led from the tank to the burner through the pipe a, as in the construction previously described. In Figs. l and 2, however, the end of the pipe is screwed into and closed by a boss, s', formed upon a.4 vertical plate of the stove.

In the application shown in Figs. 1 and 2 thehorizontal needle-valve h, with its adj uncts, is called into requisition, the aperture of its tube z' facing the open end of the tube u. The supplemental burners (represented by t t) are provided with hat-shaped caps, similar to those hereinbefore described. The supplemental burners t t" are connected by the tube u. The disk i upon the end of the needleshaft tube i keeps the vapor issuing from the aperture of said tube into the pipe u from igniting by contact with the iiame in the rear. It will be understood that the needle-valve tube i is in communication with the tube h of the needle-valve h, so that vapor used to supply the -iirst burner is also carried to the second and third burners. A projection, w, on the inner side of the pipe u is designed to deflect a portion of the vapor to the second burner,a sufficient portion being carried to the third burner; but for the use of the projection fw the second burner would receive an insuiicient supply of vapor and the third an undue supply.

By the arrangement shown in Figs. 1 and 2 enough vapor is generated by one burner to supply itself and the other two. /Ve do not restrict .oursel ves to the use together of three burners", as by making the generating-burner large enough it can be made to generate for itself and any other number of smaller ones. Suitable cleaning apertures and. plugs with stop-cocks, &c., are used in the various pipes.

Having described our invention,we claiml. The combination,with a burner, of a needle-valve in the supply-pipe, a cut-off interposed between the jet-orifice of the supplypipe and the air-tube of the burner, and a lever connected to said needle-valve and eut-off, and operating both, substantially as set forth.
